Thoma,
110mm BB is what you will want if it is a square taper remember that Campag had their own standard so you are best getting a Campag BB to got with it.
Alamara,
Your question is as confusing as the answers you have got but Malandro is right it does depend on the crank set. With a Puch you will have to check the TPI threads per inch, as these bikes were generally the cheap end of the market and tended to be imported with BB threads from the country of origin rather than British which is easiest to get here. Try the cups on another frame to confirn. 68mm is the most common width of BB and it will state that size on any BB you buy.
